The SDI Diagnostics PulmoGuard Filter Kits with Kushion Klip are high-efficiency, single-use respiratory safety packages engineered to streamline patient setups during pulmonary function testing (PFT). Developed by SDI Diagnostics, this specialized clinical configuration pre-bundles a premium pleated electrostatic barrier filter together with a foam-padded Kushion Klip nose clip inside a single hygienic wrapper. This convenience setup ensures that healthcare providers can quickly secure a patient's airway and prevent external leakage during forced expiratory maneuvers.
